Abstract
The utility model discloses a leader return rail fixing frame for an escalator. The leader return rail fixing frame for the escalator comprises a plurality of connection pieces arranged along a length direction of a leader return rail in sequence. Particularly, one end part of the connection part is fixedly arranged on a leader guide rail, and the other end part is movably arranged on the leader return rail. According to the leader return rail fixing frame for the escalator provided by the utility model, the leader guide rail and the leader return rail are connected, so that a distance between the leader guide rail and the leader return rail is unchanged in a stretching process of the leader guide rail. Therefore, the normal operation of the escalator is ensured, the dangerous coefficient of the escalator is reduced, and the occurrence rate of safety accidents is reduced. Furthermore, the leader return rail fixing frame for the escalator provided by the utility model has the advantages of simple structure, convenience in implementation and lower cost.
Description
Technical field
the main wheel that the utility model relates to a kind of staircase returns rail fixed mount.
Background technology
in existing staircase, main wheel returns rail and is substantially fixed on staircase frame, guarantee that the spacing that main wheel guide rail and main wheel return between rail is 70.5mm left and right, yet, in actual use, the bottom round end side plate of main wheel guide rail needs to stretch, and main wheel returns rail and adopts attaching parts to be fixed on staircase underframe, therefore, be difficult to guarantee main wheel guide rail when stretching and gap that main wheel returns between rail changes, thereby may cause the of short duration stuck phenomenon of chain, make staircase in running condition, easily there is the phenomenon that loiters, increase the danger coefficient that people take advantage of staircase, reduce the service life of staircase simultaneously.
Summary of the invention
technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of main wheel of staircase to return rail fixed mount.
for solving above technical matters, the utility model is taked following technical scheme:
main wheel return a rail fixed mount, it comprises and a plurality ofly along main wheel, returns the attaching parts that rail length direction sets gradually, particularly, an end of attaching parts is fixed on main wheel guide rail Shang， the other end and is arranged on actively main wheel and returns on rail.
preferably, attaching parts tool groove jaggy, the notch of groove returns the chain track between rail towards main wheel guide rail and main wheel.
according to concrete enforcement of the present utility model and preferred aspect, groove has upper cell wall, lower cell wall and for connecting the kerve wall of upper cell wall and lower cell wall, main wheel guide rail upper surface is fixedly connected with upper cell wall, and lower cell wall returns rail length direction along main wheel and is set in slidably main wheel and returns on rail.
preferably, on upper cell wall and lower cell wall, be equipped with the bayonet socket of semiclosed shape, main wheel rail welding is at the bayonet socket place of upper cell wall, and the bayonet socket of lower cell wall is arranged on sidepiece and the bottom that main wheel returns rail actively, and kerve wall caves inward along the bottom of two bayonet sockets and forms the district that dodges of chain strip side plate.
more preferably, at the bayonet socket place of upper cell wall, be provided with fillet.Prevent that main wheel guide rail is in the time of motion, bayonet socket place stress is concentrated, and causes fixed mount cracking or distortion, increases the service life of fixed mount.
due to the enforcement of above technical scheme, the utility model compared with prior art tool has the following advantages:
the utility model employing attaching parts returns rail by main wheel guide rail and main wheel and is connected, make main wheel guide rail in drawing process, the spacing that main wheel guide rail and main wheel return between rail remains unchanged, guarantee the normal operation of staircase, reduce the danger coefficient of taking advantage of staircase, reduce the generation of safety misadventure, in addition, of the present utility model simple in structure, it is convenient to implement, and cost is lower.
Accompanying drawing explanation
below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in more detail.
fig. 1 for according to the utility model main wheel guide rail, return the local structure schematic diagram of rail and fixed mount combination;
fig. 2 looks schematic diagram for return the amplification right side of rail fixed mount according to the utility model main wheel;
wherein: 1, main wheel returns rail; 2, attaching parts; 20, groove; 3, main wheel guide rail; 4, chain track; A, upper cell wall; B, lower cell wall; C, kerve wall; D, bayonet socket; E, dodge district.
The specific embodiment
as depicted in figs. 1 and 2, the main wheel of the staircase of the present embodiment returns rail fixed mount, it comprises and a plurality ofly along main wheel, returns the attaching parts 2 that rail 1 length direction sets gradually, and an end of this attaching parts 2 is fixed on main wheel guide rail 3 Shang， the other end and is arranged on actively main wheel and returns on rail 1.
above-mentioned attaching parts 2 tool groove 20 jaggy, the notch of groove 20 returns the chain track 4 between rail 1 towards main wheel guide rail 3 and main wheel, by attaching parts 2, main wheel guide rail 3 and main wheel being returned to rail 1 is connected, make main wheel guide rail 3 in drawing process, the spacing that main wheel guide rail 3 and main wheel return between rail 1 remains unchanged, and the height of chain track 4 is constant.
in this example, groove 20 has upper cell wall a, lower cell wall b and for connecting the kerve wall c of upper cell wall a and lower cell wall b, main wheel guide rail 3 upper surfaces are fixedly connected with upper cell wall a, and lower cell wall b returns rail 1 length direction along main wheel and is set in slidably main wheel and returns on rail 1.
in order to be further convenient to the connection of attaching parts 2, on upper cell wall a and lower cell wall b, be equipped with the bayonet socket d of semiclosed shape, main wheel guide rail 3 is welded on to the bayonet socket d place of upper cell wall a, the bayonet socket d of lower cell wall b is arranged on sidepiece and the bottom that main wheel returns rail 1 actively, kerve wall c along the bottom of two bayonet socket d, cave inward form chain strip side plate dodge district e.
in addition, at the bayonet socket d place of upper cell wall a, be provided with fillet, prevent that main wheel guide rail 3 is in the time of motion, bayonet socket d place stress is concentrated, and causes cracking or the distortion of attaching parts 2, extends the service life of attaching parts 2.
in sum, the utility model employing attaching parts returns rail by main wheel guide rail and main wheel and is connected, make main wheel guide rail in drawing process, the spacing that main wheel guide rail and main wheel return between rail remains unchanged, and guarantees the normal operation of staircase, reduce the danger coefficient of taking advantage of staircase, reduce the generation of safety misadventure, in addition, of the present utility model simple in structure, it is convenient to implement, and cost is lower.
above the utility model is described in detail, but the utility model is not limited to the above embodiments.All equivalences of doing according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
